Non toxic gel staining for highschool student work

As part of our NSF grant we are supposed to put on a workshop for highschool students about biotechnology. My PI would like us to do PCR and run in out on gels, but wants it to be free of ethidium bromide.

Has anyone tried Blueview from Sigma, quite pricey but they say stains DNA and RNA, or methylene blue?

Hiu can go for SRBR green gel stain for DNA on gels. its available with various vendors.http://www.cambrex.c...B...(18110).pdfbut its safe and need a extra filter to view the bands, a bit xpensive tooo.ciao

Although SYBR green is less harmful then EtBr it is still toxic. I know that CSIRO Education in Australia runs demonstrations for Schools and they use methylene blue due to saftey concerns not only with the dyes but also the UV light needed to visulise stain. I am not connected with them and probably shouldn't be volonteering them! but you may be able to get some info from them????www.csiro.au
